This guy is a great professor! He knows what's going on in the world. He is not that hard, if you can't pass him, you will have MAJOR problems in future CS courses.

Only now do I appreciate what we learned in Prof. Wang's class. I am now taking CS 60, and find myself constantly looking back over Wang's lecture notes for a refresher on the intricacies of certain ADTs. While his class is hard, it's definitely worth it.

Despite what the other reviews have said, Wang is a good teacher. He is a clear lecturer, and as long as you pay attention, it is pretty easy to understand the material. The class is also heavily curved, so even people who slack off can get good grades.

Half my class did not pass? Tell you something? Teacher did not explain or provide additional details on content. Avoid at all costs.

There is no book and the slides are nonsense, so what were we supposed to study for the midterm? The assignments are very difficult and he doesn't actually teach. He throws you into it to see if you sink or swim. Definite weeder. Avoid this guy.
